Update to 1.6.6

2011-03-12 1.6.6
- Minor IPFIX bug.
- IPFIX implement template withdraw
- For IPFIX, check packet sequence per template and observation domain
- Fix time window, when no flows collected or no flows matched
  while processing
- Fixed typos
- Fix seg fault bug - test for EMPTY_LIST was missing at several places.

2011-02-19 1.6.6b1
- Fix bps/pps. make it uint64_t, as bps/pps > 4Gb/s overflows.
- In record raw print mode: decode ICMP instead of src/dst ports
- sflow use announced exporter IP instead of sending IP for router ID
- sflow: Ignore extra fill bytes. Do not complain.
- sflow: fix packet length issue.
- Add IPFIX protokoll support

2011-12-31 1.6.5
- Fix 64bit bug when using byte/packet limits
- for v5 and sampling use 64bit counters to prevent overflow for large sampled flows.
- Fixed Ident printig bug

2011-07-11 1.6.4
- some code restructuring - prepare for IPFIX module
- Add netflow v1 module. Some routers still use that
- Add %sn, %dn output tags for src/dst networks
- Fix buffer length check in v5.
- Fix export bug: include last flow cache bucket, when exporting
- number in all filter expressions accept hex values
- fix an sflow colletor bug. Missing extension maps in rotated files
- implement extended statistics. Currently ports and bpp distribution
  vectors can be collected automatically be nfcapd. Still experimental

2011-02-26 1.6.3p1
- Fix timebug fix :(, make it a compile time option
- fix v7 sequence errors

2011-02-15
- Zero out unused fields after aggregation

2011-02-05
- Fix SysUptime 32bit overflow in v5 header
- Add fix for strange first/last swap reported by some users.

2011-01-09 v1.6.3
- Fix extension size bug
- Move IP anonymisation to separate binary nfanon
- Fix initialise bug of -o fmt: and not available fields

2010-09-09 v1.6.2
- released
- fixes some sflow bugs in sfcapd
2010-04-28 v1.6.1p0
- Update flow tools converter to build with Google-Code version 0.68.5
- Fix sflow bugs

2010-03-05 v1.6.1
- Fix bug in man page for -t
- Test sampler infos before using them ( nfcapd startup )
- Add sampling tags #34, #35 used by JunOS
- nfexpire: Fix empty .nfsat, when setting limits on an empty directory
- Fix coredump for -B -m (-w) combination
- Optimise some extension map code

2009-12-28 stable v1.6
- Few bug fixes in release candidates rc1, rc2 and rc3

2009-11-16 snapshot-1.6b-20091116
- Update sflow collector with new tags
- Add router IP extension
- Add router ID (engine type/ID) extension

2009-09-30 snapshot-1.6b-20090930
- snapshot bugfix release

2009-11-0801 snapshot-1.6b-20090806
- Add srcmask and dstmask aggregation
- Add csv output mode. -o csv
- Fix some bugs of previous beta
- Add bidirectional aggregation of flows ( -b, -B )
- Add possibility to save aggregated flows into file ( -w )
  Note: This results in a behaviour change for -w in combination
  with aggragation )
- Extend -N ( do not scale numbers ) to all text output not just summary
- Make extension handling more robust for some moody IOSes.
- Remove header lines of -s stat, when using -q ( quiet )
  Note: This results in a behaviour change for -N
- Remove -S option from nfdump ( legacy 1.4 compatibility )
- Make use of log (syslog) functions for nfprofile.
- Move log functions to util.c

2009-06-19 snapshot-1.6b-20090717
- Flow-tools converter updated - supports more common elements.
- Sflow collector updated. Supports more common elements.
- Add sampling to nfdump. Sampling is automatically recognised
  in v5 undocumented header fields and in v9 option templates.
  see nfcapd.1(1)
- Add @include option for filter to include more filter files.
- Add flexible aggregation comparable to Flexible Netflow (FNF)
- All new tags can be selected in -o fmt:... see nfdump(1)
- topN stat for all new tags is implemented
- Integrate developer code to read from pcap files into stable
- Update filter syntax for new tags
- Added more v9 tags for netflow v9.
  The detailed tags are listed in nfcapd(1)
  Adding new tags also extended the binary file format with
  data block format 2, which is extension based. File format
  for version <= 1.5.* ( Data block format 1 ) is read
  transparently. Data block 2 are skipped by nfdump 1.5.7.
  32bit but AS and interface numbers are supported.
- Add flexible storage option for nfcapd. To save disk space, the
  data extensions to be stored in the data file are user selectable.
- Added option for multiple netflow stream to same port.
  -n <Ident,IP,base_directory>
  Example: -n router1,192.168.100.1,/var/nfdump/router1
  So multiple -n options may be given at the command line
  Old style syntax still works for compatibility, ( -I .. -l ... )
  but then only one source is supported.
- Move to automake for building nfdump
- Switch scaling factor ( k, M, G ) from 1024 to 1000.
- Make nfdump fully 64bit compliant. ( 8bit data alignments and access )

2009-04-17 stable 1.5.8
- Fix daylight summer time bug, when guessing sub dirs. file access ( -M, -r )
- Bug fixes for 64bits CPUs
